shell編程系列25--shell操做數據庫實戰之備份MySQL數據，並經過FTP將其傳輸到遠端主機


備份mysql中的庫或者表

mysqldump
經常使用參數詳解：
-u    用戶名
-p    密碼
-h    服務器ip地址
-d    等價於--no-data    只導出表結構
-t    等價於--no-create-info    只導出數據，不導出建表語句
-A    等價於--all-databases
-B    等價於--databases    導出一個或多個數據庫

需求：將school中的score表備份，而且將備份數據經過ftp傳輸到 10.11.0.148(windows) 的ftp的 bak 目錄下


FTP經常使用指令：
    open    與FTP服務器創建鏈接，例子：open 10.11.0.148
    user    有權限登陸FTP服務器的用戶名和密碼，例子：user ftpuser ftpuser


# 備份school庫
[root@localhost shell]# mysqldump -udbuser -p123456 -h 10.11.0.215 school >school.sql
# 備份school庫下的score表
[root@localhost shell]# mysqldump -udbuser -p123456 -h 10.11.0.215 school score >score.sql
# -A備份全部數據庫，全部有權限的數據庫
# mysqldump -udbuser -p123456 -h 10.11.0.215 -A >score.sql
